“…Therefore, it often takes more time for tumor excision and renorrhaphy, which is most intuitively shown by longer operation time, greater WIT and blood loss.There's study indicate that hilar tumor is the independent predictor for WIT [2]. With the development of medical equipment and improvement of surgical skill, the mean WIT of most studies has been limited in 30 mins (18)(19)(20)(21)(22)(23)(24)(25)(26)(27) [2,3,13],an acceptable range. In the present study, there's no difference concerning the operation time, WIT, intraoperative blood loss and complication rate between two groups,and mean WIT in hilar tumor group is 19.8 mins,close to the result of RLPN [3].Our result has con rmed the safety and feasibility of 3DLPN for renal hilar tumors.…”

Objective To explore the feasibility of laparoscopic partial nephrectomy(LPN) in the treatment of renal hilar tumors. Methods Clinical data of 290 patients undergoing laparoscopic partial nephrectomy from January 2013 to August 2019 were retrospectively analyzed, including 27 patients with renal hilar tumors and 263 patients with non-hilar renal tumors. Perioperative data and follow-up results were compared between the two groups. Results Tumor size in Group A is smaller(2.97±0.88 vs 3.55±1.46,p<0.05), R.E.N.A.L. nephrometry score of Group A is higher(8.4±1.3 vs 6.5±1.7,p<0.01).The operation time, WIT and intraoperative blood loss in the Group A were slightly higher, but with no statistical difference (p>0.05). There was no significant difference between the two groups in intraoperative ultrasound rate, collection system repair rate, drainage time,postoperative hospital stay, and eGFR changes (p>0.05).The median follow-up period was 40 months. One patient with postoperative pathologic report of angiomyolipoma was found tumor recurrence and was currently undergoing regular reexamination. Conclusion Three-dimensional laparoscopic partial nephrectomy for renal hilar tumors is safe and feasible after detailed preoperative evaluation of the tumor and selection of appropriate surgical strategies.

“…We have also reported that self-retaining barbed suture method can improve suture e ciency and shorten WIT. For renal parenchymal reconstruction with hilar tumor, new technologies such as "V-hilar suture technique" [17] and "ring suture technique" [18] have been reported, and good clinical results have been achieved.…”

An Easy and Effective Method to Locate Renal Vein During Retroperitoneal Laparoscopic Radical Nephrectomy: Single-Center Experience

et al. 2018

BackgroundThere are few studies that address how to quickly locate the renal vein after processing the renal artery during retroperitoneal laparoscopic radical nephrectomy (RLRN) for renal cell carcinoma (RCC). This study aimed to evaluate the feasibility of an easy and effective method to locate the renal vein in RLRN.Material/MethodsBetween September 2016 and October 2017, a total of 44 consecutive cases of RLRN were performed. All the surgeries used the proposed study method to locate the renal vein, in which surgeons located the renal artery following the medial arcuate ligament on the posterior abdominal wall, then the surgeon directly searched for the renal vein caudally relative to renal artery when performing left nephrectomy, but cranially when performing right nephrectomy.ResultsAmong the 44 enrolled RLRN patients, there were 28 left nephrectomies and 16 right nephrectomies. We found the renal vein in most cases successfully by our proposed method. The renal vein was located caudally relative to the renal artery in 27 cases of the left kidney (96.4%), and was located cranially in 14 cases of the right kidney (87.5%). The mean operative time was 135.0±27.8 minutes. No intraoperative complications occurred. Postoperative complications (fever) developed in 5 patients. Pathological examination revealed: clear cell carcinoma in 34 cases (77.3%), chromophobe renal cell carcinoma (RCC) in 5 cases (11.4%), papillary RCC in 3 cases (6.8%), multilocular cystic RCC in 1 case (2.3%), and oxyphil cell adenoma in 1 case (2.3%).ConclusionsOur proposed method to search for the renal vein might be a safe and feasible procedure to accelerate the process of handling the renal pedicle and of great practical significance in RLRN surgery.

“…After induction of general anesthesia, patients were placed in our modified lateral decubitus position [13]. The distribution of the ports was similar to that previously described by us [14]. The first port was placed through a 2 cm transverse incision located 2 cm below the tip of the twelfth rib and the retroperitoneal space was bluntly created with a handmade balloon dilator.…”

Objective To evaluate the feasibility of an internal suspension technique in retroperitoneal laparoscopic partial nephrectomy for the management of renal ventral tumors. Methods Between January 2013 and July 2016, a total of 145 patients underwent retroperitoneal laparoscopic partial nephrectomy with or without internal suspension technique. For patients who underwent internal suspension technique, the surgeons preserved the external fat of the renal tumor as a suspension traction measure when separating the kidney. Propensity score matching (PSM) was performed according to age, gender, body mass index, tumor size, tumor location, and RENAL nephrometry score. Patient characteristics and intraoperative and postoperative outcomes were compared between the groups. Results After PSM, 32 patients treated with the internal suspension technique were compared with 32 cases treated without such technique. Baseline characteristics were statistically similar for the cohorts. The use of our new technique resulted in shorter warm ischemia time (WIT: 15.0 versus 19.0 minutes, P = .002) and tumor resection time (4.0 versus 7.5 minutes, P < 0.001). The rate of WIT >25 minutes decreased (6.3% versus 25%, P = .04) and the trifecta outcomes were significantly improved (87.5% versus 62.5%, P = .02). Conclusion Internal suspension technique is a feasible and safe procedure in retroperitoneal laparoscopic partial nephrectomy for renal ventral tumors.
